Description
The PC107A PCI Bridge/Integrated Memory Controller provides a bridge between the
Peripheral Component Interconnect, (PCI) bus and PowerPC 603e™, PowerPC 740™,
PowerPC 750™ or PC7400 microprocessors.
PCI support allows system designers to design systems quickly using peripherals
already designed for PCI and other standard interfaces available in the personal computer hardware environment. The PC107A provides many other necessities for
embedded applications including a high-performance memory controller and dual processor support, 2-channel flexible DMA controller, an interrupt controller, an I2O-ready
message unit, an inter-integrated circuit controller (Two-wire Interface), and low skew
clock drivers. The PC107A contains an Embedded Programmable Interrupt Controller
(EPIC) featuring five hardware interrupts (IRQ’s) as well as sixteen serial interrupts
along with four timers. The PC107A uses an advanced, 2.5V HiP3 process technology
and is fully compatible with TTL devices.

General Description
Simplified Block Diagram The PC107A integrates a PCI bridge, memory controller, DMA controller, EPIC interrupt
controller/timers, a message unit with an Intelligent Input/Output (I2O) message controller, and an Inter-integrated Circuit (two-wire interface) controller. The integration
reduces the overall packaging requirements and the number of discrete devices
required for an embedded system.
Figure 1 shows the major functional units within the PC107A. Note that this is a conceptual block diagram intended to show the basic features rather than an attempt to show
how these features are physically implemented.

PC107A [Preliminary]
Notes:
1. This pin has an internal pull-up resistor which is enabled only when the PC107A is in the reset state. The value of the internal pull-up resistor is not guaranteed, but is sufficient to ensure that a logic "1" is read into configuration bits during reset.
2. This pin is a reset configuration pin.
3. MDL[0] is a reset configuration pin and has an internal pull-up resistor which is enabled only when the MPC107 is in the
reset state.The value of the internal pull-up resistor is not guaranteed, but is sufficient to insure that a logic '1' is read into
configuration bits during reset.
4. Multi-pin signals such as AD[0–31] or DL[0–31] have their physical package pin numbers listed in order corresponding to the
signal names. Ex: AD0 is on pin D21, AD1 is on pin D23,... AD31 is on pin N23.
5. SDMA[10–1] are reset configuration pins and have internal pull-up resistors which are enabled only when the MPC107 is in
the reset state.The values of the internal pull-up resistors is not guaranteed, but are sufficient to ensure that logic "1"s are
read into the configuration bits during reset.
6. Recommend a weak pull-up resistor (2 kΩ– 10 kΩ) be placed on this PCI control pin to LVDD.
7. VIH and VIL for these signals are the same as the PCI VIH and VIL entries in Table 7, “DC Electrical Specifications.”
8. Recommend a weak pull-up resistor (2 kΩ – 10 kΩ) be placed on this pin to OVDD.
9. Recommend a weak pull-up resistor (2 kΩ – 10 kΩ) be placed on this pin to GVDD.
10. This pin has an internal pull-up resistor; the value of the internal pull-up resistor is not guaranteed, but is sufficient to prevent
unused inputs from floating.
11. This pin is affected by programmable PCI_HOLD_DEL parameter, see “PCI Signal Output Hold Timing” on page 29.”
12. This pin is an open drain signal.
13. This pin is a sustained tri-state pin as defined by the PCI Local Bus Specification.
14. See “Connection Recommendations” on page 43 for additional information on this pin.
15. A weak pull-up resistor is recommend (2 kΩ – 10 kΩ) to be placed on this pin to BVDD.
16. If BVDD = 2.5V ±5%, this microprocessor interface pin needs to be DC voltage level shifted from OVDD (3.3 ±0.3V) to 2.5V
±5%; this can typically be accomplished with a two resistor voltage divider circuit since the signal is an output only signal.

2. In this case thermal resistance junction to case is thermal resistance junction to top of Silicon die, and value almost not
depend from substrate used for land grid array. Value depends strongly on heating zone size in Silicon chip assumption. In
present simulations heating zone is 5.8 mm × 3.65 mm that is 42% of die size. Assuming the full die size as uniformly power
dissipating is not realistic.
Assuming 8.3 mm × 5.15 mm heating zone (85% of die surface) leads to 0.15°C/watt instead of 0.29°C/watt.

Thermal Management
Information
An estimation of the chip junction temperature, TJ, can be obtained from the equation:
TJ = TA + (RθJA × PD)
where
TA = ambient temperature for the package (°C)
RθJA = junction-to-ambient thermal resistance (°C/W)
PD = power dissipation in the package (W)
The junction-to-ambient thermal resistance is an industry-standard value that provides a
quick and easy estimation of thermal performance. Table 4 has four junction-to-ambient
thermal resistances (RθJA or RθJMA). Two test boards are used: single-signal-layer (1s)
and four-layer boards with two internal planes (2s2p). Which value is closer to the application depends on the system board thermal resistance and the density of other highpower dissipation components.
To illustrate the process, determine the junction temperature based on the values provided in Table 4 for an PC107 that is mounted on a board with many internal planes
using arbitrary values. If the PC107 is doing most of the power dissipation, use RθJMA of
26°C/W given in Table 4. The ambient temperature near the device is 45°C. Suppose
the total typical power dissipation at 100 MHz core frequency is 2.1W (see Table 6). The
junction temperature is:
TJ = 45 + (2.1 × 26) = 100°C.
If this value is less than the maximum junction temperature noted in Table 2, the PC107
will not need a heat sink. If the ambient temperature is higher or the power dissipation is
higher because of faster bus speed, the device will probably need a heat sink.
The PC107 may need a heat sink depending on the system. This section provides thermal management information for the flip chip plastic ball grid array (FC-PBGA) package
for air-cooled applications. Proper thermal control design is primarily dependent on the
system-level design–the heat sink, airflow, and thermal interface material. To reduce the
die-junction temperature, heat sinks may be attached to the package by several methods–spring clip to holes in the printed-circuit board or package, and mounting clip and
screw assembly (see Figure 7); however, due to the potential large mass of the heat
sink, attachment through the printed-circuit board is suggested. The force of the heat
sink on the die should not exceed 6 lb.
The heat sink surface must be flat without protrusions and must be parallel with the die
as the heat sink is brought into contact to avoid chipping the edges of the die and the
heat sink. Because of the small contact area of the heat sink, it is suggested that the
mounting force be centered over the die.

Ultimately, the final selection of an appropriate heat sink depends on many factors, such
as thermal performance at a given air velocity, spatial volume, mass, attachment
method, assembly, and cost.

Internal Package Conduction
Resistance
For the PBGA packaging technology, the intrinsic conduction thermal resistance paths
are as follows:
•
The die junction-to-case thermal resistance,
•
The die junction-to-ball thermal resistance.
Figure 8 depicts the primary heat transfer path for a package with an attached heat sink
mounted to a printed-circuit board.

The internal versus external package resistance
For this PBGA package, heat is dissipated from the component via several concurrent
paths. Heat is conducted through the silicon and may be removed to the ambient air by
convection and/or radiation. In addition, a second, parallel heat flow path exists by conduction in parallel through the C4 bumps and the epoxy under-fill, to the plastic
substrate for further convection cooling off the edges. Then from the plastic substrate,
heat is conducted via the leads/balls to the next-level interconnect (printed-circuit board)
whereupon the primary mode of heat transfer is by convection and/or radiation.

For DRV_PCI, IOH read from the IBIS listing in the pull-up mode, I(Min) column, at the 0.33V label by interpolating between
the 0.3V and 0.4V table entries’ current values which corresponds to the PCI VOH = 2.97 = 0.9*OVDD (OVDD = 3.3V) where
Table Entry Voltage = OVDD - PCI VOH.
For all others with GVDD or BVDD = 3.3V, IOH read from the IBIS listing in the pull-up mode, I(Min) column, at the 0.9V table
entry which corresponds to the VOH = 2.4V where Table Entry Voltage = G/BVDD - VOH.
For all others with BVDD = 2.5V, IOH read from the IBIS listing in the pull-up mode, I(Min) column, at the 0.65V table entry by
interpolating between the 0.6V and 0.7V table entries’ current values which corresponds to the VOH = 1.85V where Table
Entry Voltage = BVDD - VOH.
For DRV_PCI, IOL read from the IBIS listing in the pull-down mode, I(Min) column, at 0.33V = PCI VOL = 0.1*OVDD (OVDD =
3.3V) by interpolating between the 0.3V and 0.4V table entries.
For all others with GVDD or BVDD = 3.3V, IOL read from the IBIS listing in the pull-down mode, I(Min) column, at the 0.4V table
entry.
For all others with BVDD = 2.5V, IOL read from the IBIS listing in the pull-down mode, I(Min) column, at the 0.4V table entry.
For BVDD = 2.5V, the IOH and IOL values are estimated from the io_mem_data_XX_2.5 and io_mem_addr_XX_2.5 sections
of the IBIS model where XX = driver output impedance (20 or 40Ω).

These specifications are for the default driver strengths indicated in Table 8 on page 22.
Rise and fall times for the PCI_SYNC_IN input are measured from 0.4V to 2.4V.
Specification value at maximum frequency of operation.
Relock time is guaranteed by design and characterization. Relock time is not tested.
Rise and fall times for the OSC_IN input is guaranteed by design and characterization. OSC_IN input rise and fall times are
not tested.
6. Relock timing is guaranteed by design. PLL-relock time is the maximum amount of time required for PLL lock after a stable
VDD and PCI_SYNC_IN are reached during the reset sequence. This specification also applies when the PLL has been disabled and subsequently re-enabled during sleep mode. Also note that HRESET must be held asserted for a minimum of 255
bus clocks after the PLL-relock time during the reset sequence.
7. DLL_STANDARD is bit 7 of the PMC2 register <72>. N is a non-zero integer (1 or 2). Tclk is the period of one
SDRAM_SYNC_OUT clock cycle in ns. tloop is the propagation delay of the DLL synchronization feedback loop (PC board
runner) from SDRAM_SYNC_OUT to SDRAM_SYNC_IN in ns; 6.25 inches of loop length (unloaded PC board runner) corresponds to approximately 1 ns of delay. See Figure 12 on page 25 for DLL locking ranges.
8. See Table 19 on page 41 for PCI_SYNC_IN input frequency range for specific PLL_CFG[0–3] settings.

Operating Frequency
This section provides the AC electrical characteristics for the PC107A. After fabrication,
functional parts are sorted by maximum core frequency as shown in Figure 10 and
“Clock AC Specifications” on page 23 and tested for conformance to the AC specifications for that frequency. The core frequency is determined by the bus (PCI_SYNC_IN)
clock frequency and the settings of the PLL_CFG[0–3] signals. Parts are sold by maximum processor core frequency; see “Ordering Information” on page 46.
Table 10 provides the operating frequency information for the PC107A.

Notes:
1. All memory and related interface output signal specifications are specified from the VM = 1.4V of the rising edge of the memory bus clock, SDRAM_SYNC_IN to the TTL level (0.8 or 2.0V) of the signal in question. SDRAM_SYNC_IN is the same as
PCI_SYNC_IN in 1:1 mode, but is twice the frequency in 2:1 mode (processor/memory bus clock rising edges occur on

2. All PCI signals are measured from OVDD/2 of the rising edge of PCI_SYNC_IN to 0.285*OVDD or 0.615*OVDD of the signal in
question for 3.3V PCI signaling levels. See Figure 14 on page 27.
3. All output timings assume a purely resistive 50Ω load (See Figure 16 on page 28). Output timings are measured at the pin;
time-of-flight delays must be added for trace lengths, vias, and connectors in the system.
4. PCI Bussed signals are composed of the following signals: LOCK, IRDY, C/BE[0–3], PAR, TRDY, FRAME, STOP, DEVSEL,
PERR, SERR, AD[0–31], REQ[4–0], GNT[4–0], IDSEL, INTA.
5. PCI hold times can be varied, see “PCI Signal Output Hold Timing” on page 29 for information on programmable PCI output
hold times. The values shown for item 13a are for PCI compliance.

PCI Signal Output Hold
Timing
In order to meet minimum output hold specifications relative to PCI_SYNC_IN for both
33 MHz and 66 MHz PCI systems, the PC107A has a programmable output hold delay
for PCI signals. The initial value of the output hold delay is determined by the values on
the SDMA4 and SDMA3 reset configuration signals. Further output hold delay values
are available by programming the PCI_HOLD_DEL value of the PMCR2 configuration
register.
Table 13 describes the bit values for the PCI_HOLD_DEL values in PMCR2.

Description
6–4
PCI_HOLD_DEL

PCI output hold delay values relative to PCI_SYNC_IN. The initial values of bits 6 and 5
are determined by the reset configuration pins SDMA4 and SDMA3, respectively. As
these two pins have internal pull-up resistors, the default value after reset is 0b110.
While the minimum hold times are guaranteed at shown values, changes in the actual
hold time can be made by incrementing or decrementing the value in these bit fields of
this register via software or hardware configuration. The increment is in approximately
400 picosecond steps. Lowering the value in the three bit field decreases the amount of
output hold available.

1. Units for these specifications are in SDRAM_CLK/CPU_CLK units.
2. The actual values depend on the setting of the Digital Filter Frequency Sampling Rate (DFFSR) bits in the Frequency
Divider Register two-wire interface FDR. Therefore, the noted timings in the above table are all relative to qualified signals.
The qualified SCL and SDA are delayed signals from what is seen in real time on the two-wire interface bus. The qualified
SCL, SDA signals are delayed by the SDRAM_CLK/CPU_CLK clock times DFFSR times 2 plus 1 SDRAM_CLK/CPU_CLK
clock. The resulting delay value is added to the value in the table (where this note is referenced). See Figure 19 on page 34.
3. Timing is relative to the Sampling Clock (not SCL).
4. FDR[x] refers to the Frequency Divider Register I2CFDR bit x.
5. Input clock low and high periods in combination with the FDR value in the Frequency Divider Register (I2CFDR) determine
the maximum two-wire interface input frequency. See Figure 19 on page 34.

Notes:
1. Units for these specifications are in SDRAM_CLK/CPU_CLK units.
2. The actual values depend on the setting of the Digital Filter Frequency Sampling Rate (DFFSR) bits in the Frequency
Divider Register I2CFDR. Therefore, the noted timings in the above table are all relative to qualified signals. The qualified
SCL and SDA are delayed signals from what is seen in real time on the two-wire interface bus. The qualified SCL, SDA signals are delayed by the SDRAM_CLK/CPU_CLK clock times DFFSR times 2 plus 1 SDRAM_CLK/CPU_CLK clock. The
resulting delay value is added to the value in the table (where this note is referenced). See Figure 19 on page 34.
3. Since SCL and SDA are open-drain type outputs, which the PC107A can only drive low, the time required for SCL or SDA to
reach a high level depends on external signal capacitance and pull-up resistor values.
4. Specified at a nominal 50 pF load.
5. DFDR is the decimal divider number indexed by FDR[5:0] value. Refer to the two-wire Interface chapter’s Serial Bit Clock Frequency Divider Selections table. FDR[x] refers to the Frequency Divider Register I2CFDR bit x. N is equal to a variable
number that would make the result of the divide (Data Hold Time value) equal to a number less than 16. M is equal to a variable number that would make the result of the divide (Data Hold Time value) equal to a number less than 9.

Choice
The PC107A’s internal PLL is configured by the PLL_CFG[0–3] signals. For a given
PCI_SYNC_IN (PCI bus) frequency, the PLL configuration signals set the Core/Memory/Processor PLL (VCO) frequency of operation for the PCI-toCore/Memory/Processor frequency multiplying, if any. All valid PLL configurations for
the PC107A are shown in Table 19.

System Design
Information
PLL Power Supply
Filtering
The AVDD and LAVDD power signals are provided on the PC107A to provide power to the
peripheral logic/memory bus PLL and the SDRAM clock delay-locked loop (DLL),
respectively. To ensure stability of the internal clocks, the power supplied to the AVDD
and LAVDD input signals should be filtered of any noise in the 500 kHz to 10 MHz resonant frequency range of the PLLs. A separate circuit similar to the one shown in Figure
30 using surface mount capacitors with minimum effective series inductance (ESL) is
recommended for each of the AVDD and LAVDD power signal pins. Consistent with the
recommendations of Dr. Howard Johnson in High Speed Digital Design: A Handbook of
Black Magic (Prentice Hall, 1993), multiple small capacitors of equal value are recommended over using multiple values.
The circuits should be placed as close as possible to the respective input signal pins to
minimize noise coupled from nearby circuits. Routing directly as possible from the
capacitors to the input signal pins with minimal inductance of vias is important but proportionately less critical for the LAVDD pin.

Sequencing
The notes in Table 3 on page 12 contain cautions illustrated in Figure 3 on page 13
about the sequencing of the external bus voltages and internal voltages of the PC107A.
These cautions are necessary for the long term reliability of the part. If they are violated,
the electrostatic discharge (ESD) protection diodes will be forward biased and excessive
current can flow through these diodes. Figure 3 shows a typical ramping voltage
sequence where the DC power sources (voltage regulators and/or power supplies) are
connected as shown in Figure 31. The voltage regulator delay shown in Figure 3 can be
zero if the various DC voltage levels are all applied to the target board at the same time.
The ramping voltage sequence shows a scenario in which the VDD/AVDD/LAVDD power
plane is not loaded as much as the OVDD/GVDD power plane and thus VDD/AVDD/LAVDD
ramps at a faster rate than OVDD/GVDD.
If the system power supply design does not control the voltage sequencing, the circuit of
Figure 31 can be added to meet these requirements. The MUR420 diodes of Figure 31
control the maximum potential difference between the 3.3 bus and internal voltages on
power-up and the 1N5820 Schottky diodes regulate the maximum potential difference
on power-down.

Decoupling
Recommendations
Due to the PC107A’s dynamic power management feature, large address and data
buses, and high operating frequencies, the PC107A can generate transient power
surges and high frequency noise in its power supply, especially while driving large
capacitive loads. This noise must be prevented from reaching other components in the
PC107A system, and the PC107A itself requires a clean, tightly regulated source of
power. Therefore, it is recommended that the system designer place at least one decoupling capacitor at each V DD , OV DD , GV DD , and LV DD pin of the PC107A. It is also
recommended that these decoupling capacitors receive their power from separate VDD,
OVDD, GVDD, and GND power planes in the PCB, utilizing short traces to minimize inductance. These capacitors should have a value of 0.1 µF. Only ceramic SMT (surface
mount technology) capacitors should be used to minimize lead inductance, preferably
0508 or 0603, oriented such that connections are made along the length of the part.
In addition, it is recommended that there be several bulk storage capacitors distributed
around the PCB, feeding the VDD, OVDD, GVDD, BVDD, and LVDD planes, to enable quick
recharging of the smaller chip capacitors. These bulk capacitors should have a low ESR
(equivalent series resistance) rating to ensure the quick response time necessary. They
should also be connected to the power and ground planes through two vias to minimize
inductance. Suggested bulk capacitors-100 – 330 µF (AVX TPS tantalum or Sanyo
OSCON).
Connection
Recommendations
To ensure reliable operation, it is highly recommended to connect unused inputs to an
appropriate signal level. Unused active low inputs should be tied to OVDD. Unused active
high inputs should be connected to GND. All NC (no-connect) signals must remain
unconnected.
Power and ground connections must be made to all external VDD, OVDD, GVDD, LVDD,
BVDD, and GND pins of the PC107A.
The PCI_SYNC_OUT signal is intended to be routed halfway out to the PCI devices and
then returned to the PCI_SYNC_IN input of the PC107A.
The SDRAM_SYNC_OUT signal is intended to be routed halfway out to the SDRAM
devices and then returned to the SDRAM_SYNC_IN input of the PC107A. The trace
length may be used to skew or adjust the timing window as needed. See Motorola application note "AN1794/D" for more information on this topic.
The TRST signal must be asserted during reset to ensure proper initialization and operation of the PC107A. It is recommended that the TRST signal be connected to the
system HRESET signal or pulled down with a 100Ω - 1 kΩ resistor.
43
2137C–HIREL–03/04
Pull-up/Pull-down
Resistor Requirements
The data bus input receivers are normally turned off when no read operation is in
progress; therefore, they do not require pull-up resistors on the bus. The processor data
bus signals are: DH[0–31], DL[0–31], and PAR[0–7]. The memory data bus signals are:
MDH[0–31], MDL[0–31], and PAR/AR[0–7].
If the 32-bit data bus mode is selected, the input receivers of the unused data and parity
bits (DL[0–31], DP[4–7], MDL[0–31], and PAR[4–7]) will be disabled, and their outputs
will drive logic zeros when they would otherwise normally be driven. For this mode,
these pins do not require pull-up resistors, and should be left unconnected by the system to minimize possible output switching.
It is recommended that ARTRY, TA, and TS have weak pull-up resistors (2 kΩ – 10 kΩ)
connected to BVDD.
It is recommended that MTP[1–2] and TEST2 have weak pull-up resistor (2 kΩ – 10 kΩ)
connected to GVDD.
It is recommended that the following signals be pulled up to OVDD with weak pull-up
resistors (2 kΩ – 10 kΩ): SDA, SCL, TEST1, and FTP[3–3].
It is recommended that the following PCI control signals be pulled up to LVDD with weak
pull-up resistors (2 kΩ – 10 kΩ): DEVSEL, FRAME, IRDY, LOCK, PERR, SERR, STOP,
TRDY and INTA. The resistor values may need to be adjusted stronger to reduce
induced noise on specific board designs.
The following pins have internal pull-up resistors enabled at all times: REQ[06–4], TCK,
TDI, TMS, and TRST, BR1, HRESET_CPU, MCP, QACK, SRESET, TEST and
TRIG_OUT. See Table 1, “PC107A Pinout Listing,” on page 5 for more information.
The following pins have internal pull-up resistors enabled only while device is in the
reset state: MDL0, FOE, RCS0, SDRAS, SDCAS, CKE, SDBAO, and SDMA[10–1]. See
Table 1, “PC107A Pinout Listing,” on page 5 for more information.
The following pins are reset configuration pins: MDL0, FOE, RCS0, SDBAO, SDMA[10–
1], and PLL_CFG[0–3]. These pins are sampled during reset to configure the device.
Any other unused active low input pins should be tied to a logic one level via weak pullup resistors (2 kΩ – 10 kΩ) to the appropriate power supply listed in Table 3 on page 12.
Unused active high input pins should be tied to GND via weak pull-down resistors
(2 kΩ– 10 kΩ).
